Which is the best exhaust brake for the money, and what kind of mods will need to be done to the auto on an 07 5.9? I had a jacobs on my 06 5.9 6spd and loved it.....so what do you all have, and what kind of tranny mods should be done to make the tranny last????

PACBRAKE Enough said!

You might want to look into the warranty issues since you have a new truck. From what I've read, only the Jacobs (when installed by a dealer) is fully covered by both the standard and factory extended warranties and will not potentially void the factory warranty.

I personally prefer the Pacbrake design (compressed air vs vacuum actuation), but I'd hate to have a breakdown 2000 miles from home and have to contend with a dealer who says the Pacbrake is an "unauthorized modification".

They are both good and about the same price from what I've seen.

not so the brake will not void warranty the packbrake or bd brake works 2x better than jake or banks and no vacuum pump to go bad and when you upgrade the exhaust housing on the turbo the vacuum cylinder gets in the way on the banks and jake

Another vote for Pacbrake.

anything that needs to be done to beef up the trans??

Nope the tranny is fine the way it is on the 06 & 07 for exhaust brake use

I asked my dealer about the Pac brake before i had it installed. THey gave me the thumbs up and even RECOMMENDED it. They said it is a superior design and as long as it does not cause a component to fail I am alright. I know SEVERAL DODGE DEALERS that install the Pac brake/

I just put the Pacbrake on my 06 and love it. Towing my trailer today and can't wait to see how well it works. Installation wasn't bad. I was a little nervous but all went well. I checked with my dealer before I purchased it and I was told that as long as any problems I had weren't caused by the brake then my warranty was fine. But as we all know it all depends on who you talk to as dealers sometimes make up their own rules. Dealer wanted almost $1800 for Jacobs w/installation. I got the Pacbrake from DTR store and saved a lot doing it myself. Pacbrake is a great company to deal with. I contacted their tech service a couple of times to make sure I was doing it right. They were very helpful.

Unfortunately that is up to interpretation by the dealer. I won't argue that in most cases you will be okay, but I've seen too many threads where the dealer wants to be an azz regarding mods and then you are stuck fighting an expensive law suit (while your truck sits broken and the payments are still due).

On the Dodge, Jacobs and Cummins websites it specifically states that the installation of the Jacobs brake will not void the Dodge factory warranty.... you won't find that on the Pac or BD websites. The Moss/Magnusson Act deals with things like oil & air filters, fanbelts and other replacement/service items, not aftermarket hardware and & mods.

That may be true, however I believe pacbrake does have a warranty. They stand behind their product. If the brake causes a part to fail, they will cover the cost of the repair. Dealer might not but they will. From an engineering standpoint, I have heard that the Pacbrake is less likely to cause harm than some other approved brakes. After talking with harold myself he explained that Pacbrake got all the tech info on Back pressure tolerances from Cummins. And they designed their brake around those parameters.

I know PacBrake is a good (maybe better) product, but I would want to see the Consequential Damages Warranty in writing. I don't yet have an exhaust brake, but I did call the DC Warranty 800 number and was told that only the Jacobs was approved by Dodge.

All I'm saying is get all the facts before making a decision. Let's say my engine drops a valve, eats a piston and scores the crankshaft 3000 miles away from home. What if the local dealer says that the aftermarket brake caused the problem? I would have the option of paying for the repair and fighting it later or storing the truck there while the issue is resolved or having it transported home waiting for a resolution of the warranty dispute. With the Jacobs unit I have it in writing that it is covered by both the standard 3/36 and my extended 7 year 100K service plan.

I suggest calling the Dodge Warranty 800 number (not your local dealer) to get the final word on what is or is not covered.

Best,

John

I do see your point!!! And I agree! I did LOTS of research prior to having the brake installed. I Sent a PM to Harold-Pacbrake again to get his take on it. I never buy anything on a whim and made sure I did my homework...

palomino

you guys definately bring up a valid point about the waranty concerns. The pac-brake unit uses an electric compressor right, and I know the jacobs uses a belt driven pump.
